Re: Looking for uci engines with piece value options shown

I will be testing/improving an spsa tuner at https://github.com/fsmosca/spsa. I am primarily interested on uci engines with settable piece values. Deuterium has and I am looking for others to try. What I will do is to weaken the engine by unoptimizing its piece value and try the tuner if it can imp...

Re: Why do the latest Sergio Vieri 384x30b networks scale so badly?

Here is the result for 6s+0.1s How many time forfeits did you get running that timecontrol? I tried reproducing your results with similar conditions and I got a ridiculous number of time forfeits. More than 10%. I ran 5s+0.08 as I have a faster GPU and wanted to be close to your nodes/move. Perhaps...

Re: Why do the latest Sergio Vieri 384x30b networks scale so badly?

Thanks! I guess MLH shouldn't change Elo, if Leela was trolling in the endgames without actually missing conversion? But does MLH change the goal from scoring optimization to something like scoring + moves left optimization? That would change Elo. It’s an extra head, so a little bit of a slowdown. ...

I suspect you don’t have MLH turned on.

Which version of lc0 and which mlh settings are you using?
v0.25.1 cudnn-fp16
No MLH settings (moves left head, right?). They are not accessible via easy to use UCI settings and I don't know what values to put anyway.

Re: Why do the latest Sergio Vieri 384x30b networks scale so badly?

Another badly scaling net from SV, 384x30-t60-4206.pb.gz. All the nets since 3290 LR 0.02 have the same bad scaling. It might explain the current performance in TCEC SuFi, although only 25 or so games were played. 6s + 0.1s Score of SV_384x30_4206 vs SV_384x30_3010: 461 - 352 - 187 [0.554] 1000 ... ...
